BATTERY LAMP.

Application filed. August 1C,` 1921. Serial No. 491,160.

T 0 all whom t may concern.'

Be it known that I, EDGAR J. MGEACH- RON, a citizen ot the UnitedStates, residing at Madison, in the county ot Dane and State ofiVisconsin, have invented a new and useiiul improvement in BatteryLamps, of which the following is a speciication.

rl`his invention relates particularly to iiashlights, lanterns orhand-lamps ot the type employing` a tubular casing` and a dry cell ordry cells confined in said casing. ln a device of this character,according to usual practice, the cell or cells are tree to move somewhatin the tubular casing, the front or upper cell being pressed against thebase of the lamp by means cit a spring confined in the bottom ot thecasing.

The object oi' the present invention is to provide a simple and cheapdevice adapted to guard the lamp against shock arising from the shiftingof the dry cells within the casing.

The invention is illustrated, in its preferred embodiment, in theaccompanying drawing, in which- Figa l represents an elevational view ofa hand-lamp equipped with the improved device, the upper portion of thehand-lamp being` shown in section; and Fig'. 2, an enlarged brokensectional view showing the reflector ot the hand-lamp equipped with theimproved shock-absorbing; device, the dotted lines indicating theposition of the dry cell with relation to said device.

ln the construction illustrated, A represents the tubular handle orcasing' of the hand-lamp or Hash-light, fitted at one end with a ring orannular mounting A, and fitted at the other end with a removable cap A2;B, a metallic reflector which is provided with a central tubular shankB; C, a lens; D, a retaining ring for the lens which has threadedconnection with the member A; E, a dry cell provided with a carbon poleE; and F, the improved shock-absorber or bumper applied to the shank Bof the reflector.

The spring which is usually employed in the base portion of the tubularmember A is shown in dotted lines and is designated G.

The shank B of the reflector preferably is provided with internalthreads and external threads. Preferably, this is accomplished byspinning or pressingthe metal of the shank so that a somewhat coarsethread rlhe member F preferably is made of insulating` material, such ashard fiber, vulcanized iber, or the like. kThis member preferably is atubular member provided with a bore 2 at one end and with an end wall 3at the other end. rlhe member 2 yis internally threaded to screw ontothe shank B, as shown in Fig. 2. Thru the end wall 3 ofthe member Fextends a central contact i which is adapted to bear against the carbonpole E. This is shown as in the form ot a rivet 4l. The wall 3 isrecessed as indicated a't 3ZL to receive iireely a small coil spring' 5which has its inner or lower end secured to the adjacent end of therivet 4. Secured to the outer or upper end of the spring 5 is a smalldisk 5a which bears against the central contact l of the lampshank. Thedisk 5 may be suitably secured 'to the sprinpgvin any desired manner, asby soldering.

lWhen the parts are assembled in the manner shown in Fig. 2, the springcontact 5 or terminal with which the insulation bloc r F is equippedpresses the lamp forwardly so that it is yieldingly held against 'theetherwise loose fitting' threads.

In use, the member F and the spring contact with which it is equippedserve effectually to prevent shocks from being transmitted from the cellor cells to the lampbulb, it being noted that the insulation block, orsocket-men'iber F, is securely attached to the shank of the reiiector Band the relector is, in turn, securely held on its seat by theretaining-ring` D and the interposed peripheral. portion ot' thereliector C.

The construction described is suited to use in connection with areflector or" standard type` it being usual to provide the reliectorwith a corrugated thread. Thus, the bumper block may be applied withoutchanging,- the construction. Moreover, this form of device enables alight and comparatively long spiral spring,` to be used, so that thedanger of the lamp being injured 'is reduced to a minimum.

The hand-lamp is shown provided with an internal contact member 6 whichengages the hef "d as new7 end desire to secure by Letters VFatemi, is-
